Moosmom almost took the words right out of my mouth! Bats are very beneficial to the environment, and totally harmless creatures. I love watching them swooping and using their radar to zero in on an insect! I used to live in an apartment building, and for some reason our weird downstairs neighbor would get bats in her place every now & then. One day Tina comes screaming up at our door saying "there's a bat in my hamper"! I went and rescued the bat and set it outside again....and was sooo tempted to say to her that it probably fell out of her head! But I was nice. Enjoy the show...it's free, and think of all the hundreds of mosquitos being consumed every evening.
